A British pint is a fifth larger than an American one
The imperial pint is 568.26125 ml and the US liquid pint is 473.176473 ml, so a pint of beer in London is 20% more beer than a pint in New York. Both are called a pint and both are legal measures. The gap comes from the gallons they divide: the imperial gallon is 4.54609 liters against the US gallon’s 3.785411784, and every fraction below them inherits the difference.
NIST Handbook 44, Appendix C — general tables of units of measurement
What is an imperial pint?
An eighth of an imperial gallon, 568.26125 ml exactly, and still the legal measure for draught beer and doorstep milk in the UK. A US pint is 473 ml, which is why a British pint glass holds noticeably more.
What is a US pint?
Two US cups, about 473 ml. A UK pint is 568 ml — a fifth larger.
How many US pints are in an imperial pint?
One imperial pint is 1.2009499 US pints. Going the other way, one US pint is 0.83267418 imperial pints. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
